        public static java.util.Map<java.lang.String,​java.util.Set<java.util.Set<java.lang.String>>> getUniqueKeySets​(java.util.Properties options)
        Returns the parsed value of the UNIQUE_KEY_SETS option. Takes String of unique keys, grouped by parentheses, delimited by commas and a returns a Map from each referenced table to the set of key sets. Uses default function that splits table and column on last dot. e.g.: 
         ("Table1"."Column1"), ("Table1"."Column3", "Table1"."Column4"), (mongocol.[unwind1;unwind2].unwind1.field1)
        is parsed to: 
         {""Table1"" : [[""Column1""], [""Column3"", ""Column4""]]},
 {"mongocol.[unwind1;unwind2]" : [["unwind1.field1"]]}
